Pentaconn Coreir Brass Eartips

The brass core acts as a rigid, stable structure that helps maintain the shape of the eartip and prevents sound distortion. This material choice is designed to improve acoustic reflection and clarity, resulting in a more precise sound signature compared to standard silicone tips.

Each box contains two pairs of Pentaconn Coreir Brass Eartips.

Pentaconn offers four sizes: S, MS, M, and L. If you are unsure of your fit, we recommend measuring the nozzle diameter of your current in-ear monitors or trying a size that matches your most comfortable existing eartips, as the brass core makes these slightly less flexible than all-silicone options.

These eartips are designed to fit a wide range of in-ear monitors, but compatibility depends on the nozzle diameter of your specific earphones. Because of the rigid brass core, they are best suited for standard nozzle sizes; extremely wide or proprietary nozzle shapes may not seat properly.

Yes, the combination of the dense brass core and the high-quality outer material creates a more effective seal in the ear canal. This improved seal generally leads to better passive noise isolation, which helps block out ambient sound and enhances bass response.
